Introduction:
In this lab, you will configure IPv6 BGP neighborship between all ISP's using their respective IPv6 addresses of loopback0 interfaces.


Lab Tasks: 

1. Access CLI of all ISP routers, verify IPV6 connectivity between ISPs' loopback0 interfaces. 

2. Establish BGP session over IPV6, between ISP1 and ISP2, using their loopback 0 interfaces as update-source. 

3. Establish BGP session over IPV6, between ISP1 and ISP3, using their loopback 0 interfaces as update-source. 

4. Establish BGP session over IPV6, between ISP1 and ISP4, using their loopback 0 interfaces as update-source. 

5. Establish BGP session over IPV6, between ISP2 and ISP3, using their loopback 0 interfaces as update-source. 

6. Establish BGP session over IPV6, between ISP3 and ISP4, using their loopback 0 interfaces as update-source.  

7. Verify BGP neighborship over IPV6 on all ISPs' routers. 

8. Save running-config. 



Configuration example:
!
ISP1(config)# router bgp  101 
ISP1(config-router)# neighbor 2001:DB8:102:1000::100 remote-as 102
ISP1(config-router)#neighbor  2001:DB8:102:1000::100 update-source lo0 
ISP1(config-router)#neighbor  2001:DB8:102:1000::100 ebgp-multihop 2 
ISP1(config-router)# address-family ipv6 
ISP1(config-router)# neighbor 2001:DB8:102:1000::100 activate 
ISP1(config-router)# exit-address-family 

Verify BGP session over IPv6: 
!
ISP1# show bgp ipv6 unicast summary
